Stress urinary incontinence treatment medical implant
The present invention provides an implant that includes inflatable anchors that are configured to assume an inflated state and a relaxed state. The implant includes a tubular member mechanically coupled to one or more anchors of the inflatable anchors. The tubular member includes a lumen that provides a passageway for circulating a fluid through the one or more of the plurality of inflatable anchors and allow them to protrude and pierce through bodily tissues. In an embodiment, the implant may include a plurality of bi-directional barbs instead of the inflatable anchors. The plurality of barbs may be activated by a flexible member such that the activation is configured to cause anchoring of the barbs into soft tissues during a surgical procedure. The present invention provides a method for placing an implant. The method includes delivering the implant inside a body along a pathway through an opening proximate sacrum and attaching a first portion of the implant to an anterior vaginal wall, attaching a second portion of the implant to a posterior vaginal wall and attaching a third portion of the implant to a tissue proximate the sacrum.
1. A n implant for treatment of stress urinary incontinence, the implant comprising:
an elongate body member with a proximal portion, a distal portion, and an intermediate portion, wherein the intermediate portion is configured to be positioned proximate a weakened tissue underneath urethra to provide support;
a plurality of bi-directional barbs positioned on an outer surface of the elongate body member, the plurality of barbs including a first set of barbs directed to a first direction and disposed proximate the proximal portion wherein the first set of barbs are disposed in a series of at least two rows with each row containing at least four barbs and a second set of barbs directed to a second direction and disposed proximate the distal portion wherein the second set of barbs are disposed in a series of at least two rows with each row containing at least four barbs, wherein the plurality of barbs are configured to assume an exposed state and a relaxed state;
a plurality of first flexible members, wherein each of the plurality of first flexible members is attached to the at least four barbs of a row of the first set of barbs, and a plurality of second flexible members, wherein each of the plurality of second flexible members is attached to the at least four barbs of a row of the second set of barbs such that each row of the at least four barbs is activated through a different flexible member of the plurality of first flexible members and the plurality of second flexible members, wherein the plurality of first flexible members and the plurality of second flexible members are configured to cause the first set of barbs and the second set of barbs respectively to assume the exposed state from the relaxed state upon activation such that the activation is configured to cause anchoring of exposed barbs into soft tissues during a surgical implant of the implant.
2. The implant of claim 1 , wherein each of the plurality of barbs include a base portion and a sharp tip portion, the sharp tip portion configured to pierce the soft tissues for fixation of the implant.
3. The implant of claim 2 , wherein the sharp tip portion defines a curved shape that is configured to engage with the soft tissues once a barb is in the exposed state.
4. The implant of claim 1 , wherein each of the plurality of barbs include a slot for associating a respective flexible member with a barb.
5. The implant of claim 1 , wherein in the exposed state, the plurality of barbs protrudes outward from an outer surface of the elongate body member.
6. The implant of claim 1 , wherein the plurality of barbs are biased to remain in the relaxed state and assume the exposed state upon activation after placement of the implant at a target site.
